You don't say what you've set the IDs of the controllers to in this 
diagram.  As a general rule, though, I think that what you're trying to 
do is probably not going to be possible (I see signs of "I can share this 
array between two machines" thinking above).

As for why Linux doesn't detect that it's sent a command and then lost it 
- who knows?  One more reason not to use it, I guess, since I certainly 
value my SCSI I/O commands.
